This has been more than a decade so my recollection may be off.

I was not doing anything that require very clear perception.  It was a home
toy project albeit with practice home-automation use.
I think it was something like 12bit or 24bit.   Somehow, that number comes
to my mind when I saw your question.
But again, I could be off

That page speaks of Pocketsphinx, an apparently current version is in 
the Debian repository. Synaptic reports "This package contains end-user 
speech recognition tools", so it should be good start.

The site has valuable background information.

Do you recall the sample bit depth and rate - [so I could compare to 
hardware I'll be looking at].

I had the first Wikipedia article. The software listing of the TLDP 
reference may be dated but the whole article appears to be good guidance 
for more research.

Anything involving Google is a non-stater!

This is an old issue that pops up in Web 2.0-ish winky blink sites with
lots of java/flash/javascript and the occasional memory leak  Often a
bit of FF stays in memory and gets lost and you'll just have to kill it
with extreme prejudice.   FF can and will suck up memory and CPU cycles.

If you linked in from another site to youtube, I doubt there was a
nefarious payload - Google would not want the bad press.  The issue most
likely was either flash, or some other site heap full of javascript
embedded advertisements.

There are a few speech recognition engines that are F/OSS.  A brief
summery is here:
https://en.wikipedia.org/wiki/Speech_recognition_software_for_Linux
https://en.wikipedia.org/wiki/List_of_speech_recognition_software

Some leverage Googles speech API - and everything you say gets uploaded
to Google.  There are several engines and frontends for GTK and KDE
(QT).  Quality can be a bit rough, but that depends on your accent and
how the software engine was/is  trained.

It's been awhile since I played with any of this stuff. The Google API
was pretty good, but tended to lag a bit - perhaps better now.
